Abstract
A method and apparatus classifies and grades glossiness based on the visible feeling by the light reflection intensity distribution of a surface of a body, wherein specular reflection intensities and total reflection intensities are detected for two known light fluxes projected at predetermined incident angles. The specular reflection intensities and the total reflection intensities are processed, to thereby determine the glossiness of the work to be measured.
